yes
No, you can take the melted chocolate goo and pour it into a mold, cool it and re-form the candy bar. No, melting a chocolate bar is not an irreversible change. Melting a chocolate bar is just changing its state of matter. If you but the melted chocolate bar in a freezer, where exothermic processes will occur, and the chocolate bar will be solid again.
Melting a candy bar is a physical change because it is just changing form, not changing the chemical makeup. (If it isn't making a new material, it is not a chemical change)
Melting is endothermic. Freezing is exothermic.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
endothermic
candy bar
A candy bar becomes a tasty drink when it is transformed into a liquid form, typically through a process such as melting or blending. This can be achieved by heating the candy bar until it melts into a liquid consistency, or by blending it with a liquid such as milk or water to create a smooth, drinkable mixture. The resulting beverage will retain the flavors of the original candy bar, providing a unique and indulgent drinking experience.
Speed Racer's favorite candy bar is a Japenese Candy Bar.
It is an endothermic process.
No. It is a candy but not a bar.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
The answer is candy bar because it does not have to be baked
